Definitions
- the invention relates to a device for eliminating a resistance welding produced burrs in the manufacture of metallic rim tapes according to the Preamble of claim 1.
- the Resistance pressure welding of the sheet bent into a pipe section a more or less large compression ridge.
- the size of this compression ridge depends on the type of Welding, i.e. whether flash butt welding or pressure butt welding and from Material, i.e. whether steel or light metal.
- the upsetting ridge particularly large, especially with regard to the radial extension and the following one Cutting effort is considerable in order to remove this compression ridge. So far it has been common to remove the edging ridge in layers by lifting it several times. It can occur that the chip rolls heavily and the sharp edges the Damage the workpiece surface. This is particularly on the later outside of the rock in most cases not tolerable, especially since elimination by hand Grinding takes place and at the same time the inadmissible weakening of the wall thickness that is possible must be observed.
- the device consists of an elongated deburring tool that can be arranged in the tube Can be positioned in the longitudinal direction via a rod connected to it.
- the leadership in the pipe take over several roles arranged on the deburring tool, which are on the inner wall support the pipe.
- the actual tool is designed as a roller knife, which on one Bracket is attached, which in turn is releasably connected to the deburring tool.
- the Roller knife is arranged at two inclinations, on the one hand inclined with respect to the Cross-sectional plane and in relation to the diameter plane enclosing the upsetting ridge.
- This double inclination was chosen so that the roller knife by the feed of the Endless strand of the pipe is rotated.
- welding performance is the time-determining factor, so that cutting performance achievable with the deburring tool is of secondary importance.
- the service life of the rolling knife is more important, as each replacement to a standstill Welding line leads.
- the rolling knife is in the form of a truncated cone, the Taper lies in the direction of the attachment.
- JP-A-57-075297 describes the manufacture of a wheel. Starting from one Sheet metal strip this is formed into a round bandage, the two ends of which over one Resistance pressure welding are integrally connected. After removal of the compression ridge created inside and outside is the rim bandage on the exact Cut width. Then the inside is polished and after several Forming steps made the rim. The rim is given the final dimension by a Expander process. The surfaces are then polished and the wheel rim is ready.
- the object of the invention is a device for eliminating a Resistance pressure welding produced upsetting burrs in the manufacture of metallic Specify rim bandages with which in a short cycle time without damaging the surrounding Workpiece surface of the compression ridge is removed.
- the device according to the invention provides a lateral one Cut into the edging ridge, just above the surrounding one Workpiece surface.
- the fact that the compression ridge is at this point is used has only a relatively narrow web. By cutting in on the side, it rolls No longer cut and the known damage on the surrounding This avoids material surfaces.
- the tools used are as standing knife or designed as a rolling knife, which in the longitudinal direction of the upsetting ridge movable tool carriers are attached.
- To cut in the standing To facilitate knives is the cutting edge lying in the cutting direction in relation to the Longitudinally slanted and the cross section perpendicular to it is wedge-shaped. The the latter feature also applies to the roller knives.
- To support the incision have the jaws on the clamping side facing the compression ridge knife-shaped nose.
- Figure 3 shows in the same cross section as in Figure 1, a second embodiment of the Device according to the invention, the same reference numerals for the same parts have been used.
- roller knives 11, 12 In contrast to the embodiment in FIG. 1, instead of the standing knives 7, 8 roller knives 11, 12 attached to the movable tool carrier 6, 6 '. Axes 13, 14 of the rolling knives 11, 12 are at an angle to the axis of the tool carriers 6, 6 '. By this inclination is on the side facing away from the upsetting ridge 4, 5 Generates free space, the unhindered rolling movement of the rolling knives 11, 12th ensures. Comparable to the standing knives, the rolling knives 11, 12 have Cutting area a wedge-shaped cross section. To support the side The jaws 2, 3 cut into the cutting ridge 4, 5 facing side each have a nose 15, 16, which is wedge-shaped in cross section are.
